I'm 50/50 on it I guess; they can be really flairy and bounce light about all over the place. I tend not to use them, but do have them in the bag, and put them on if I think it is beneficial, like if I an climbing just for a bit of added protection. I heard a great story too about two wildlife photographers out looking for a moose bull, whilst tracking the animal down it snowed, so the lenses were covered (they both had filters on) on getting in range discovering their lenses were covered, one struggled to clean off the snow, the other whipped off the filter and got the shot! His companion got a shot of the mooses rear vanishing into the trees lol Thats life.

The Truth is Out There
